Modified invocation services such that providers are responsible for

delivering their own responses. They now have all the information
necessary to do so which means that they can delay the delivery of a
response until some other asynchronous event has taken place (like a
database load completing). Prior to this, they were required to complete
their service immediately and return the response back to the invocation
manager.
